Roller Machine Safety Precautions
1. Avoid cuts by always wearing gloves when handling sheet metal.
2. Keeps hands and clothes out of the path of the rollers.
3. The Roller Machine should only be used by an experienced operator.
Unpacking
When unpacking, check to make sure the following parts are included:
- Roller Machine - 7 Dies - 3 Hex Wrenches
If any parts are missing or broken, please call Harbor Freight Tools at the number on the
cover of this manual as soon as possible. Parts of this machine come coated with a rust
inhibitor. It must be removed before using. Refer to the Maintenance section on page 8.
Operation
The Roller Machine is used for shearing and rolling sheet metal up to 18 gauge. The Roller
Machine comes pre-adjusted from the factory. Before using it, however, check that all the
necessary adjustments are made (Refer to the section on Adjustments).
Pressing
1. Raise the Lower Braking Die (11) to its highest level by rotating the Handle Arm (18).
2. Slide the Press Plate Brackets (8) of the Press Plate Assembly (8,9,10,54) into the
receiver holes of the Lower Braking Die (11).
Note that the Press Plate (10) should be facing down.
3. Raise the Press Plate (10) as necessary by turning the Hex Bolt (54) clockwise.
4. Place the workpiece so that it is centered under the Press Plate (10).
5. Rotate the Handle Arm (18) to press the workpiece.

Page 5SKU 43353
Shearing
1. Scribe the cutting mark on the sheet metal.
2. Slide the sheet metal between the upper Blade (23) and the lower Blade (23) so that
the upper Blade (23) is positioned directly over the cutting mark.
If additional cuts of identical size are needed, the Backstop (21) can be adjusted to the
required depth. The sheet metal will stop on the Backstop (21) when inserted. Refer to
the Adjustments section, Adjusting the Backstop.
3. While holding the material steady, rotate the Handle Arm (18) until the material has
been cut.
For large pieces of sheet metal, it may be necessary to use a front table to support the
metal, or have someone hold it for you.
Angle Bending
1. Mark the sheet metal where it is to be bent.
2. Place the sheet metal above the Lower Braking Die (11).
3. Align the bending mark with the front edge of the Upper Die (12).
If multiple bends of identical size and angle sheet metal are needed, the Backstop (21)
can be adjusted to the required depth. The sheet metal will stop on the Backstop (21)
when inserted. Refer to the Adjustments section, Adjusting the Backstop.
4. Rotate the Handle Arm (18) until the desired angle been formed.
Use a protractor or other measuring tool to ensure accuracy.
Radius Bending
Radius bending is most commonly used to make cylinders and cones. Both shapes are
formed by making a series of small, closely spaced bends in the work piece. For cylinders,
the bends are even spaced. For cones, move one side of the sheet metal further out each
time a bend is made.
Pan Bending
The Angle Bending feature can be used to make various sizes of pans out of sheet metal.
The maximum lip (side) height is 1 inch.
1. Pre-measure and cut your material before bending.
Notch the corners to the desired lip (side) height.
2. Place the sheet metal above the Lower Braking Die (11).
3. Align the bending mark with the front edge of the Upper Die (12).
4. Rotate the Handle Arm (18) until 90 degree angle been formed.

Page 6SKU 43353
Use a protractor or other measuring tool to ensure accuracy.
5. Rotate the sheet metal 90 degrees counterclockwise.
Allow the completed side to extend just beyond the Dies.
6. Bend the sheet metal. Repeat step 5 for the 3rd side.
7. Rotate to the final side and insert the sheet metal lip between the Dies.
The formed sides will be on the outside of the Dies.
8. Before bending the 4th side, tap one corner nearer the middle of the machine.
This will allow the sides to clear the upper Die (12) when raised.
Rolling
1. Lift the front Cover (33) and flip backward, out of the way.
2. Drop the Rear Roll Bar (24) by loosening the Adjustment Knob (25b).
3. Insert only the leading edge of the sheet metal between the Upper Roll Bar (32) and
the Lower Roll Bar (31), tighten the Adjustment Keys (27) until the Roll Bars are just
snug against the sheet metal.
4. Advance the Adjustable Bolt (25b) to the desired tightness for the roll.
The more the Adjustable Bolt (25b) is advanced, the tighter the roll.
5. Turn the Handle Arm (18) until the desired roll is achieved.
The sheet metal should feed itself through the rollers as the Handle Arm (18) is turned.
Wire Rolling
1. Select the proper size groove in the Upper Roll Bar (32) depending upon the gauge of
the wire being rolled.
2. Follow steps 2 through 5 (above), under Rolling.
Adjustments
While making adjustments, it may be necessary to refer to the Assembly Drawing at the end
of this manual
Handle Removal and Adjustment
The Handle Arm (18) may be adjusted or removed by removing one of the Handle Knob
Assemblies (26a, 26b, 61) and loosening the Knob (59) that holds the Handle Arm (18) in
place. It may then be slid out of the handle socket.
Bending Die Adjustment and Removal
The Upper Die (12) is segmented and can be used for varying sizes of box and pan forming.
When forming a smaller box or pan, choose the desired size Upper Die (12) finger, center it
and remove the others.

Page 7SKU 43353
The Roller Machine can be used to bend sheet metal up to 18 gauge. The space between
the Upper Die (12) and the Lower Braking Die (11) is adjustable as described below.
1. Place a piece of flat, straight wood (or metal place) between the Upper Die (12) and
Lower Braking Dies (11) and raise the Lower Braking Die (11) so that the material just
touches the Upper Die (12).
2. Loosen the Hex Head Screws (51) holding the Upper Die (12) in place.
Do not remove the Screws.
3. Remove any unnecessary Upper Die (12) fingers.
4. Raise the Lower Braking Die (11), using the long piece of wood or metal plate as a
level guide, adjust the alignment of the Upper Die (12) fingers.
5. When aligned, retighten the Hex Head Screw (51).
Removal and Installation of the Upper Cutting Blade (23)
1. Remove the six Hex Head Screws (55) holding in the upper cutting Blade (23).
2. Remove (or replace) the upper cutting Blade (23), and replace the Screws but do not
tighten completely.
3. Align the upper cutting Blade (23) so that it is flush with the Lower Braking Die (11).
4. Tighten all the Hex Head Screws (55).
Adjustment of the Upper Cutting Blade
1. Place a 30 inch piece of thin cardboard or paper between the upper and lower Blades
(23).
2. Rotate the Handle Arm (18) and cut the material.
3. Use a straightedge to determine the straightness of the cut and if the Blade (23) is in
need of adjustment.
4. If the Blade (23) is bowed out (away from the front of the machine), turn the adjustment
Nut (48) counterclockwise.
This will tighten the Adjustment Bar (22) and push the middle of the upper Blade (23)
out, while pulling in its ends.
5. If the Blade (23) is bowed in (towards the back of the machine), turn the adjustment Nut
(48) clockwise.
This will loosen the Adjustment Bar (22) and pull the middle of the upper Blade (23) in,
while pushing its ends out.
Removal and Installation of the Lower Blade
1. Remove the Hex Head Screws (57) from the lower cutting Blade (23).
2. Remove (or replace) the lower cutting Blade (23).
